FMRP regulates the subcellular distribution of cortical dendritic spine density in a non-cell-autonomous manner

Neurobiology of Disease, 2021
Fragile X syndrome (FXS) is the most common form of intellectual disability that arises from the dysfunction of a single gene—Fmr1. The main neuroanatomical correlate of FXS is elevated dendritic spine density on cortical pyramidal neurons, which has ...

The influence of sex, genotype, and dose on serum and hippocampal cytokine levels in juvenile mice developmentally exposed to a human-relevant mixture of polychlorinated biphenyls

Current Research in Toxicology, 2020
Polychlorinated biphenyls (PCBs) are pervasive environmental contaminants implicated as risk factors for neurodevelopmental disorders (NDDs). Immune dysregulation is another NDD risk factor, and developmental PCB exposures are associated with early life ...

Prevalence of cytogenetic abnormalities and FMR1 gene premutation in a Portuguese population with premature ovarian insufficiency

Acta Médica Portuguesa, 2021
Introduction: Chromosome abnormalities contribute to about 10% of cases of premature ovarian insufficiency. Most are associated with X chromosome. Fragile mental retardation 1 (FMR1) gene premutation has an estimated prevalence of 1% - 7% in sporadic ...

Plasma Biomarkers for Monitoring Brain Pathophysiology in FMR1 Premutation Carriers. [PDF]

, 2016
Premutation carriers have a 55-200 CGG expansion in the fragile X mental retardation 1 (FMR1) gene. Currently, 1.5 million individuals are affected in the United States, and carriers are at risk of developing the late-onset neurodegenerative disorder ...

miRNA expression and interaction with the 3′UTR of FMR1 in FRAXopathy pathogenesis

Non-coding RNA Research, 2021
FRAXopathies are caused by the expansion of the CGG repeat in the 5′UTR of the FMR1 gene, which encodes the protein responsible for the synthesis of FMRP.

Identifying specific prefrontal neurons that contribute to autism-associated abnormalities in physiology and social behavior. [PDF]

, 2017
Functional imaging and gene expression studies both implicate the medial prefrontal cortex (mPFC), particularly deep-layer projection neurons, as a potential locus for autism pathology.

Phenotypical and Genotypical Expansion of Autosomal‐Dominant KDM1A‐Related Neurodevelopmental Disorder Spectrum: A Case Report

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT KDM1A‐related neurodevelopmental disorder (CPRF, OMIM #616728) is characterized by cleft palate, global developmental delay, and distinct facial gestalt, but phenotypic knowledge of this ultra‐rare autosomal dominant disorder is limited. Here, we report on a 13‐year‐old boy with a novel heterozygous, likely pathogenic germline missense variant

Deficient Sleep in Mouse Models of Fragile X Syndrome

Frontiers in Molecular Neuroscience, 2017
In patients with fragile X syndrome (FXS), sleep problems are commonly observed but are not well characterized. In animal models of FXS (dfmr1 and Fmr1 knockout (KO)/Fxr2 heterozygote) circadian rhythmicity is affected, but sleep per se has not been ...

Fragile X Messenger Ribonucleoprotein 1 (FMR1), a novel inhibitor of osteoblast/osteocyte differentiation, regulates bone formation, mass, and strength in young and aged male and female mice

Bone Research, 2023
Fragile X Messenger Ribonucleoprotein 1 (FMR1) gene mutations lead to fragile X syndrome, cognitive disorders, and, in some individuals, scoliosis and craniofacial abnormalities. Four-month-old (mo) male mice with deletion of the FMR1 gene exhibit a mild

Voltage-independent SK-channel dysfunction causes neuronal hyperexcitability in the hippocampus of Fmr1 knock-out mice [PDF]

, 2019
Neuronal hyperexcitability is one of the major characteristics of fragile X syndrome (FXS), yet the molecular mechanisms of this critical dysfunction remain poorly understood. Here we report a major role of voltage-independent potassium (
